Module Name:

    Procdep.c

Abstract:

    This module contains the entry points for the processor dependent
    extensions for ntvdm.exe.

Author:

    Dave Hastings (daveh) 1-Apr-1992

Notes:

    All of the processor dependent extensions should be entered through
    this module.  This will allow us to easily insure that both the MIPs
    and x86 version of ntvdm export all of the entry points specified in
    ntvdm.def.

    The processor specific code should be put into a private function in
    the i386 or Mips directory.
